Eine Blind-SQL-Injection ist eine besondere Form von SQL-Injection, bei der die Einschränkung besteht, Daten nur indirekt auslesen zu können. Das ist beispielsweise bei. This lab contains an SQL injection vulnerability in the product category filter. When the user selects a category, the application carries out an SQL query like the following: SELECT * FROM products WHERE category = 'Gifts' AND released = 1 To solve the lab, perform an SQL injection attack that causes the application to display details of all products in any category, both released and. Most of the time when we talk about SQL injection we extract data by using the union keyword, error based, blind boolean and time based injection methods. All this comes under a place where the application is performing a SELECT statement on the back-end database

An SQL injection is a technique that attackers apply to insert SQL query into input fields to then be processed by the underlying SQL database. These weaknesses are then able to be abused when entry forms allow user-generated SQL statements to query the database directly SQL-Injection (dt.SQL-Einschleusung) ist das Ausnutzen einer Sicherheitslücke in Zusammenhang mit SQL-Datenbanken, die durch mangelnde Maskierung oder Überprüfung von Metazeichen in Benutzereingaben entsteht. Der Angreifer versucht dabei, über die Anwendung, die den Zugriff auf die Datenbank bereitstellt, eigene Datenbankbefehle einzuschleusen

Time-Based Blind SQL Injection Attacks; Analysing Server Response and Page Source; Database Fingerprinting for SQL Injection; SQL Injection Using UNION. Understanding how to create a valid UNION-based attack to extract information. UNION-based attacks allow the tester to easily extract information from the database. Because the UNION operator can only be used if both queries have the exact. SQL Injection (SQLi) is often considered an injection attack wherein an attacker can execute malignant SQL statements. That control a web application's database server. Since a SQL Injection helplessness could influence any site or web application that makes utilization of a SQL-based database The main thing with SQL injection is user controlled input (as is with XSS). In the most simple example if you have a form (I hope you never have one that just does this) that takes a username and password. SELECT * FROM Users WHERE Username = ' + username + ' AND password = ' + password +

SQL injection, or SQLi, is an attack on a web application by compromising its database through malicious SQL statements. As it's a common attack, let's try to learn more about what it is, how it happens, and how to defend yourself from it SQL Injection Cheat Sheet What is an SQL Injection Cheat Sheet? An SQL injection cheat sheet is a resource in which you can find detailed technical information about the many different variants of the SQL Injection vulnerability.This cheat sheet is of good reference to both seasoned penetration tester and also those who are just getting started in web application security SQL Injection. 03/16/2017; 11 minutes to read +4; In this article. Applies to: SQL Server (all supported versions) Azure SQL Database Azure SQL Managed Instance Azure Synapse Analytics Parallel Data Warehouse SQL injection is an attack in which malicious code is inserted into strings that are later passed to an instance of SQL Server for parsing and execution SQL injection is a technique where malicious users can inject SQL commands into an SQL statement via web page input. And this input may be quite different - the text field in form, _GET or _POST parameter, cookies etc. This method was really effective before frameworks become so trendy in PHP world SQL Injection. Many web developers are unaware of how SQL queries can be tampered with, and assume that an SQL query is a trusted command. It means that SQL queries are able to circumvent access controls, thereby bypassing standard authentication and authorization checks, and sometimes SQL queries even may allow access to host operating system level commands

Protecting Yourself from SQL Injection in SQL Server - Part 1. By: Aaron Bertrand | Updated: 2015-05-27 | Comments (1) | Related: 1 | 2 | More > SQL Injection. Problem. Many of us are using dynamic SQL because we have requirements that dictate runtime choice - allowing the user to select the columns, or table name, or even entire where clauses. There are different ways to implement dynamic SQL. SQL Injection ausnutzen ==>2.1. An Ziele gelangen / Lücke finden. Am einfachsten ist der Angriff auf eine Seite durch einen GET-Paramter.

Today, I'm going to explain what a SQL injection attack is and take a look at an example of a simple vulnerable PHP application accessing a SQLite or MySQL database. After that, we'll look at several methods to prevent this attack, fixing the problem. Prerequisites. Make sure you have the following.

SQL Injection Attacks (SQLi) — Web-based Application

SQL injections are possible when data search as user input enters the SQL interpreter. For those who have special functions for the SQL interpreter and thus allow external influence on the executed database commands. Search metacharacters in SQL are for example \ ' and This results in an SQL injection UNION attack. Example union attack. The UNION keyword lets you execute one or more additional SELECT queries and append the results to the original query. For example We're going to get to work our way up to SQL injection attacks and the reason they are scarier than a clown who lives in a drainpipe. But in order to understand injection/vulnerabilities, we need to take a step back and review that basic SQL knowledge first, which you may not have needed until this point in your role as a sysadmin. SQL and Sysadmins. If you were interviewing a Sysadmin for a. SQL Injection (SQLi) is the type of injection attack that makes it possible to execute the malicious SQL statements. These statements control the database server behind a web application. The SQL Injection vulnerability may affect any website or web application that uses the SQL database such as SQL Server, MySQL, Oracle, SQL Server, or others. Cyber Criminals may use it to gain unauthorized. Okay After Enough of those injection we are now moving towards Bypassing Login pages using SQL Injection. Its a very old trick so i got nothing new other than some explainations and yeah a lil deep understanding with some new flavors of bypasses. Okay rather than making the Tutorial very i long i will go point by point. Note before reading this if you have not read the Basic SQL injection then.

  5. Let's see a very simple example of how a SQL injection attack can be executed on a database server. Consider a scenario where you have a web application that accesses the BookStore database that we created in the last section. Your web application has a search box where a user can enter the name of a book and, if the book exists, the id, name, and price of the book is shown on the webpage

The SQL Injection usually occurs when you ask a user for input, like their name and instead of a name they give you a MySQL statement that you will unknowingly run on your database. Never trust the data provided by a user, process this data only after validation; as a rule, this is done by pattern matching. In the following example, the username is restricted to alphanumerical characters plus. How to perform SQL Injection depends upon how the web application is built. So attackers must initially find out about the structure of web application and its application code. The attacker finds out the method by which data is passed to the web application. Once he knows this, he will proceed to SQL Injection. There are 2 ways by which data is passed to the web application. 1.) GET Method. 2. The word Injection means to inject something in your system and SQL Injection means injecting some SQL in your database system for hacking it to steal your information such has Username and Passwords for authentication or causing harm to your system by deleting data or dropping tables SQL Injection (SQLi) is an injection attack where an attacker executes malicious SQL statements to control a web application's database server, thereby accessing, modifying and deleting unauthorized data

specifically discussing Transact-SQL, the dialect of SQL used by Microsoft SQL Server. SQL Injection occurs when an attacker is able to insert a series of SQL statements into a 'query' by manipulating data input into an application. A typical SQL statement looks like this: select id, forename, surname from authors This statement will retrieve the 'id', 'forename' and 'surname' columns from the. In the previous case, the injected SELECT statement will be valid in every case as long as the first query only selects 2 columns (on MySQL and SQL Server). If the column expects a text, the number will be considered as a string, otherwize it will be considered as a numeric value. As you can guess, building a valid query becomes much easier. SQL HOME SQL Intro SQL Syntax SQL Select SQL Select Distinct SQL Where SQL And, Or, Not SQL Order By SQL Insert Into SQL Null Values SQL Update SQL Delete SQL Select Top SQL Min and Max SQL Count, Avg, Sum SQL Like SQL Wildcards SQL In SQL Between SQL Aliases SQL Joins SQL Inner Join SQL Left Join SQL Right Join SQL Full Join SQL Self Join SQL.

SQL injection is one of the most common code injection attack methods, in which malicious SQL statements are inserted to execute unauthorized SQL statements in the database, e.g. read data or modify data in the database. They can be inserted as input by the user through the user interface or by a program through the parameter interface from outside. Two SQL injection variants can be found in. SQL Injections. SELECT ASCII('a') CHAR() (SM) Convert an integer of ASCII. SELECT CHAR(64) Union Injections With union you do SQL queries cross-table. Basically you can poison query to return records from another table. SELECT header, txt FROM news UNION ALL SELECT name, pass FROM members This will combine results from both news table and members table and return all of them. Another Example.

SQL Injection. Viele Entwickler sind sich nicht bewusst, wie man sich an SQL Abfragen zu schaffen machen kann und nehmen an, dass eine SQL Abfrage ein vertrauenswürdiges Kommando ist. Das heißt, dass SQL Abfragen Zugriffskontrollen hinters Licht führen, und dadurch Standard Authentifizierungs- und Authorisationschecks umgehen können, und manchmal können SQL Abfragen sogar Zugriff zu. This type of SQL injection is possible only for some databases, for example, Microsoft SQL Server and Oracle. The attacker includes a special database command in the payload - this command causes a request to an external resource (controlled by the attacker Unter einer SQL-Injection (dt. SQL-Einschleusung) versteht man das Ausnutzen einer Sicherheitslücke in relationalen Datenbankensystemen, die bei der Dateneingabe auf die Sprache SQL zurückgreifen. Der Angreifer macht sich dabei solche Benutzereingaben in die Datenbank-Oberflächen zunutze, die nicht ausreichend maskiert sind und Metazeichen wie den doppelten Bindestrich, Anführungszeichen.

SQL Injection is an attack that poisons dynamic SQL statements to comment out certain parts of the statement or appending a condition that will always be true. It takes advantage of the design flaws in poorly designed web applications to exploit SQL statements to execute malicious SQL code. In this tutorial, you will learn SQL Injection techniques and how you can protect web applications from. There are lot of excellent SQL injection cheat sheets out there; however, I found the majority provide only the components of a SQL injection rather a Executed Query: select * from tbluser where userId=132 Result: Query will return data of user having userId 132. No SQL Injection is happening in this case. 2. Hacker User Input. A hacker can alter user requests using tools like Postman, cURL, etc. to send SQL code as data and this way bypassing any UI side validations SQL Injection eliminated at the server where it matters. Filtering can not achieve the same result. Chris Saxon Thursday, October 6, 2016. Interesting idea. You're proposing a whitelist of permitted statements based on their hash? Oracle already computes a hash based on the text. That's what the SQL_ID is. So in theory this is possible. If you're not using bind variables each statement will. SQL injection can be used to manipulate the application's web server by malicious users. SQL injection generally occurs when we ask a user to input their username/userID. Instead of a name or ID, the user gives us an SQL statement that we will unknowingly run on our database. For Example - we create a SELECT statement by adding a variable demoUserID to select a string. The variable will be.

An SQL Injection attack can successfully bypass the WAF , and be conducted in all following cases: • Vulnerabilities in the functions of WAF request normalization. • Application of HPP and HPF techniques. • Bypassing filter rules (signatures). • Vulnerability exploitation by the method of blind SQL Injection. • Attacking the application operating logics (and/or) WAF Bypassing Strings. SQL Injection is the exploitation of a SQL database vulnerability caused by the lack of masking or validation of metacharacters in user input. if you any assistance to SQL Injection then write my assignment. Consequences: The attacker is ready to deal with a successful attack, to spy on data, modify it or delete it altogether, and gain control of the server. Functionality: SQL injections are. Often, when there is one SQL injection, there are many-and they are easily exploitable with tools like sqlmap. Occasionally, an application is largely protected against SQL injection, but something interesting happens on a test. A tester manually validates a SQL injection vulnerability based on server responses, knows the database, sqlmap supports the database-but sqlmap fails. Even manual.

  1. By: Tim Smith | Updated: 2019-01-28 | Comments | Related: More > SQL Injection Problem. We use dynamic SQL in a customer facing application and throughout our data's life cycle, as it allows us and customers to use the data in a range of table objects that we and our customers may need to use for reports or data. We think this is convenient since it saves us time in development and also allows.
  2. SQL injection is the attack in which the user of the website will input some SQL code as input which would result in creating a SQL statement that developers didn't intend to write. These SQL statements could result in unauthorized access, revealing secret user information and sometimes it could even wipe out the entire data lying on the server
  3. SQL injection easiness can vary a lot depending on the details of the server's SQL request and the processing applied to the result. It's all up to your luck factor here. Nevertheless, manually building a successful SQL injection string always boils down to this loop: Inject a request in the server. Observe the result
  4. SQL Injection Attacks are very common throughout the web. Hackers are known to use malicious SQL queries to retrieve data directly from the database. It basically exploits a security vulnerability. They are most common in online applications where the inputs are not correctly filtered. Consider the following code

  6. SQL injection is a subset of an even larger exploit known as an injection, which also includes application code, web components, networking hardware, and the other various components that make up the framework of an application. This threat is the most frequent and consistently rated top security exploit in the history of database software. Despite years of research, identification, and.
  7. That is good. we are on the right track now lets start the Blind SQL injection. Why we call it blind as we cant see anything we dont know anything what we do is just keep asking question from the database and get the reply in form of yes (Page loaded Normally) or NO (Page dint Loaded Normally). There are again Two Ways for Blind SQL injection 1.

Awareness workshops are a platform where general security topics or specific questions — like what is SQL injection, and how to prevent SQL injection attacks — can be addressed to keep your staff updated on the kinds of security incidents that are prevalent. However, security requires a transformation in attitude to avoid negligent practices. Until that happens, mandatory training and. In order to bypass this security mechanism, SQL code has to be injected on to the input fields. The code has to be injected in such a way that the SQL statement should generate a valid result upon execution. If the executed SQL query has errors in the syntax, it won't featch a valid result. So filling in random SQL commands and submitting the form will not always result in succesfull. Opinion: On the presence of SQL and SQL injections in Star Trek Don't worry, I'll keep this brief. I just want to add my thoughts to the fan reaction that Federation starships are still running SQL-compatible databases a couple of hundred years from now, and that Federation software developers didn't think to protect against SQL injection attacks Hi there, I have SQL 2008 R2 server, it is hacked by SQL injection attack. How can find the malicious code? how to protect the sql injection again? Thanks, stephen · Most of these queries are from SQL Server Agent, Policy Based Management or metadata queries from SSMS. And if you have the database off the hook, it is not surprising that. Dynamic SQL is a mechanism which is used to programmatically generate and execute T-SQL statements. With the help of SQL Server sp_execute, that may be using programming languages like C#, C++ etc., or using the stored procedure to execute the dynamic query

Durch diese SQL-Injection kann ein Angreifer an sämtliche Daten eurer Datenbank gelangen. Nicht nur SELECT-Anweisungen sind gefährdet, sondern sämtliche Daten die ihr an die Datenbank sendet. So können auch UPDATE, INSERT und DELETE-Anweisungen entsprechend manipuliert werden. Habt ihr beispielsweise den folgenden SQL-Query: 1 $ sql = UPDATE user SET vorname='. $ _POST ['neuer_vorname. This wikiHow teaches you how to prevent SQL injection using Prepared Statements in PHP. SQL injection is one of the most common vulnerabilities in Web applications today. Prepared Statements use bound parameters and do not combine variables with SQL strings, making it impossible for an attacker to modify the SQL statement SQL injection is a technique where users can inject SQL commands into an SQL statement, via web page input. The injected SQL commands can alter SQL statement leading to security issues. Consider a webpage which allows a user to input User ID and r.. SQL injection was very common years ago. It was just this simple. With a better knowledge of SQL and some really tortured syntax, a good hacker can do almost anything he wants with an SQL injection like this. About the Book Author. Stephen R. Davis is the bestselling author of numerous books and articles, including C# For Dummies. He has been programming for over 30 years and currently works. In SQL injection attacks, stacked queries are typically used in order to update data in the database in case there is a SQL injection defect in a 'SELECT' statement. This is important since the 'SELECT' statement cannot have an 'INSERT' or 'UPDATE' statement as a sub-select query, so in this case it must be done through stacked SQL queries. On the other hand, if there is a SQL.

What is SQL Injection? Tutorial & Examples Web Security

Blind SQL injection is nearly identical to normal SQL Injection, the only difference being the way the data is retrieved from the database. When the database does not output data to the web page, an attacker is forced to steal data by asking the database a series of true or false questions. This makes exploiting the SQL Injection vulnerability more difficult, but not impossible. Diese an sich gut gemeinte Fehlerabfangroutine hat den Nachteil, dass sie sich leicht ausmanövrieren lässt, wenn die Eingabe nicht gefiltert wird. Wird über ein Formularfeld ein einfache A 'blind' SQL injection vulnerability is when the attacker can send commands to the database but they don't actually see the database output. What is the impact of a SQL injection vulnerability? In the following video, we create a WordPress plugin that contains a SQL injection vulnerability. Then we demonstrate how to attack our test website and exploit the vulnerability. We get a list. Bypass all WAF in SQL Injection hello friends today i will tell you how to bypass all WAF in SQL injection WAF stands for web applica... Bypass all WAF in SQL Injection. hello friends today i will tell you how to bypass all WAF in SQL injection WAF stands for web application firewalls. waf is used to detect malicious script which we inject in a web application. Almost every WAF can be bypassed.

SELECT * FROM table_name WHERE username='Raj'-+' AND password='Chandel'; But our database will read and execute only. SELECT * FROM table_name WHERE username='Raj' this much query because everything after -+ will be commented and will not be interpreted as part of the query. This is what is called SQL INJECTION. Changing the. 4.0 How do I get remote execution with SQL injection? Being able to inject SQL command usually mean, we can execute any SQL query at will. Default installation of MS SQL Server is running as SYSTEM, which is equivalent to Administrator access in Windows. We can use stored procedures like master..xp_cmdshell to perform remote execution: '; exec master..xp_cmdshell 'ping'- Try.

Server variables such as HTTP headers can also be used as a SQL injection attack vector. Forged headers containing arbitrary SQL can inject that code into the database if the web application fails. Use the SQL Injection cheat sheet. Most databases have a way to query the version e.g. SELECT @@version. If you have already found an injectable point that returns data try a couple of those until you get data back. example methodology: SELECT @@version # fails. Then you know it is not MS SQL or MySQL. SELECT version() # fails. You know it is.

SQL-Injection: Erklärungen mit Beispielen und Lösungsansätze

Taking advantage of SQL injection in ORDER BY clauses is tricky, but a CASE statement can be used to test other fields, switching the sort column for true or false. While it can take many queries, an attacker can determine the value of the field. params[:sortby] = (CASE SUBSTR(password, 1, 1) WHEN 's' THEN 0 else 1 END) User.order( #{params[:sortby]} ASC ) Query. SELECT users .* FROM. The attacker can inject SQL that tests if the first letter of a tablename entry in the data dictionary starts in the first half of the alphabet; if true, then test if the first letter is in the first quarter of the alphabet, and so on until the attacker has guessed the first letter of the table name; and then do the same for the second letter and so on, until the attacker has guessed the table. SQL-Injection-Angriffe nutzen Schwachstellen der Structured Query Language (SQL), die gewöhnlich in relationalen Datenbanken verwendet wird, um Datenbanken außer Gefecht zu setzen oder in sie einzudringen. Sie werden immer mehr zu einem vorherrschenden Mittel, um Websites zu sabotieren und zu unterwandern und so die Funktionalität einer Website in vielerlei Hinsicht zu stören. SQL. SQL code injection. This is a little demonstration of a SQL injection in a simple application. In our example, a database as been provisionned with an admin user. Their credentials are: username: admin password: admin123 In theory it should only be possible to in the application using this credential, but if the application is not safely programmed, it is possible to penetrate in.

Lab: SQL injection vulnerability in WHERE clause allowing

Test your website for SQL injection attack and prevent it from being hacked. SQLi (SQL Injection) is an old technique where hacker executes the malicious SQL statements to take over the website.It is considered as high severity vulnerability, and the latest report by Acunetix shows 8% of the scanned target was vulnerable from it.. Since SQL (Structured query language) database is supported by. The reason behind that is the protection that developer had applied to prevent SQL injection, sometimes developer use filters to strip out few characters and OPERATORS from the user input before adding it to the query for SQL statement to prevent SQL Injection. Today's article will help you to face such situations and will tell you how to bypass such filters. Here again, we'll be using. A SQL injection attack is an attack that is aimed at subverting the original intent of the application by submitting attacker-supplied SQL statements directly to the backend database. Depending on the web application, and how it processes the attacker-supplied data prior to building a SQL statement, a successful SQL injection attack can have far-reaching implications. The possible security. SQL Injection is a technique that allows an adversary to insert arbitrary SQL commands in the queries that a web application makes to its database. It can work on vulnerable webpages and apps that use a backend database like MySQL, Oracle, and MSSQL. A successful attack can lead to unauthorized access to sensitive information in the database or to modifying entries (add/delete/update. SQL Injection binary (Boolean) exploit utilizes the fact that we inject and execute a condition or sub-query on data stored in the database which will return either a TRUE or FALSE answer; the TRUE and FALSE answers must produce a different behavior that is detectable at the client side. For example (Injected values are bolded): Select * from table where column = '' and 1=1.

So in this paper I am going to discuss about 2 techniques of SQL Injection exploitation if database is SQLite. 1. Union based SQL Injection (numeric as well as string based) 2. Blind SQL Injection. Lab environment: To work with SQLite database based SQL Injection, we need following things on our machine. 1. Web server (apache in my case) 2. PHP. SQL Injection (SQLi) Cheat Sheet, Attack Examples & Protection SQL Injection, sometimes shortened to SQLi, is perhaps the most commonly employed hacking technique today, constantly making headlines and appearing in vulnerability reports. These malicious injections have been regularly starring in the OWASP Top-10 lists for years and they took the first place in the 2013 OWASPRead More (Animation of the simplest SQL Injection - feel free to go to Altoro Mutual try to hack their - it's safe - you won't get in trouble, this site was made to demonstrate web vulnerabilities.) The innocuous credential SQL search. SELECT userid FROM members WHERE username = 'admin' AND password='DifficultPassword!' is modified by the attacker by entering admin'- in the SQL injection is to execute only SQL statements whose text derives entirely from the source code of the PL/SQL program that executes it. However, when the watertight approach will not meet the requirements, it is, after all, necessary to handle user input — and to do so safely. A careful study of this topic is presented in the section Ensuring the safety of a SQL literal or a simple SQL. To perform SQL Injection in target website, we are going to use Pro version of Havij SQL Injection Tool as in free version, we are going to miss some very essential features. Well, if you want you can do a quick search to download free version of Havij automatic SQL Injection software or just be smart and download Havij Pro free using below URL

How to Prevent SQL Injection: Attacks and Defense

SQL-Injection - Wikipedi

NoSQL injection vulnerabilities allow attackers to inject code into commands for databases that don't use SQL queries, such as MongoDB. NoSQL injection attacks can be especially dangerous because code is injected and executed on the server in the language of the web application, potentially allowing arbitrary code execution SQL Injection (aka Structured Query Language Injection) is the first step in the entry to exploiting or hacking websites. It is easily done and it is a great starting off point. SQLi is just basically injecting queries into a database or using queries to get authorization bypass as an administrator

SQL Injection Using UNIO

  1. e whether the SQL query string is malformed. All they can do is send a string to the database.
  2. SQL injection attacks take advantage of an application's vulnerability to user input that is either incorrectly filtered for string literal escape characters with embedded SQL statements, or input that is not strongly typed. The following section discusses the two types of security vulnerability that can promote an SQL injection attack. Incorrectly filtered escape characters. In the first type.
  3. Values obtained from the user are parsed to ensure SQL injection doesn't happen. Code for String Concatenation. Public Shared Function insecureLogin(userName As String, passWord As String) As String Dim conn As MySqlConnection = getConnection(details) Dim command As New MySqlCommand(SELECT userName FROM Users WHERE userName=' & userName & ' AND passWord=' & passWord & ', conn) Dim o As.
  4. SQL injection is a variety of techniques that all have the goal of. letting an attacker run whichever SQL statements they want in your database. Unlike many hacking techniques the attacker is not.

SQL Injection is like a real-life injection. Using SQL Injection you can get important information or you can insert some information into the database. Here, the user tries to into a web application using their credentials. Only authenticated users can into the application. But a hacker can input malicious data and to the web application even though they are not. SQL injection is a web security vulnerability that allows an attacker to interfere with the queries that an application makes to its database.It generally allows an attacker to view data that they are not normally able to retrieve. This might include data belonging to other users, or any other data that the application itself is able to access.In many cases, an attacker can modify or delete. SQL Injection is a software vulnerability that occurs when user-supplied data is used as part of a SQL query. Due to improper validation of data, an attacker can submit a valid SQL statement that changes the logic of the initial query used by the application. As a result, the attacker can view/modify/delete sensitive data of other users or even get unauthorized access to the entire system. SQL SELECT Statement. In this tutorial you will learn how to select records from database tables using SQL. Selecting Data from Table. In the previous chapter we've learned how to insert data in a database table. Now it's time to select the data from existing tables using the SQL query SQL injection has become a common issue with database-driven web sites. The flaw is easily detected, and easily exploited, and as such, any site or software package with even a minimal user base is likely to be subject to an attempted attack of this kind. This flaw depends on the fact that SQL makes no real distinction between the control and data planes. Relationships. The table(s) below.
